The change most people with a bad back are chasing is simple: a surface that stops the pelvis dropping lower than the shoulders. Ashley's 12-inch Chime does that with a medium-firm memory foam top over a three-layer build, and after sleeping on it we think it is the most sensible first stop in this roundup. The firmness is real, but it is not the plank that supportive usually gets translated into.
Medium firm is the least standardized term in bedding, so here is how this one behaves. It gives under the shoulders and hips and then stops. Back and stomach sleepers get on with it immediately, and so do heavier side sleepers, who have enough weight to press into the top layer. Lighter side sleepers are the group it can miss: without that weight the surface reads hard at the shoulder, and no amount of contouring language fixes that.
Two practical details are worth knowing before you order. The care instructions ask for a thin, breathable protector rather than a quilted pad, because a pad changes the feel you chose and traps the heat the foam is meant to let go of, which is sensible advice almost everyone ignores. And the foundation is not in the box, so plan for a platform bed or a box spring if you do not already have one. Adjustable bases are listed as compatible, which matters if you sleep with the head raised.
